CORN-PLANTER.

Specification of Letters Patent.

Patented Feb. 27, 1912.

Application filed October 22, 1910. Serial No. 588,442.

To all whom'z't may concern:

Be it known that I, FRANK P. MURPHEY, a citizen of the United States,residing at Decatur, in the county. of Macon and State of Illinois, haveinvented certain new and useful Improvements in Corn-Planters, of

which the following is a specification.

The present invention relates to the construction of the frameworkconstituting the body of the planter; to the manner of arranging thisframework, whereby a separate frameis provided for supporting theplanter mechanism and for supporting the seat; to a connection betweenthe framework supporting the planting mechanism and the inner coveringwheels; to the construction and arrangement of the covering wheels; tothe manner of adjusting the inner covering wheels and the shovels of theplanting mechanism; and to the distribution and counterbalancing of theweight of the various portions of the planter.

-Among the objects of the present invention the most important is: to soconstruct and arrange the outer or traction wheels that they will serveboth as carrying and as covering wheels, when acting preferably inconjunction with a pair of inner covering wheels of smaller diameter,and so arranged with respect to the furrow openers that the latter willenter the ground at a point slightly 1n advance of the point of groundcontact for the covering wheels and immediately in line with the spaceintermediate the two covering wheels.

A further object of the invention pertains to the means whereby theinner covering wheels may be adjusted in line with the furrow openers orat any other position with respect to the furrow opener that may bedesired.

The invention further relates to the construction and manner of mountingthe seed boxes, each of which is provided with a discharge from theouter side of the box at a point directly above the furrow openers,thereby enabling the seed boxes to be located in close proximity to andimmediatelyinside of the outer carrying and covering wheels rather thanat a point in advance of or above the rims of the wheels. Thisarrangement brings the discharge openings for the seed boxes intorelatively close proximity to the ground, which facilitates drilling andat the same time brings the seed box in toward the supporting axle ofthe machine, thereby more nearly centering the weight.

The invention further relates to the formation and relative positioningof the covering wheels with respect to one another, and particularly tothe beveled formation of the rims, which serve to throw the soil in fromeach side toward the opening created by the advancing furrow openers,thereby covering the grain Without top contact from the covering wheel.

Further objects of the invention pertain to the construction andarrangement of the framework and to the means provided for adjusting thevarious portions of the machine with respect to one another.

The invention further consists in the feaof the bar and supporting therunner; Fig.

6,'a section on line 66 of Fig. 5 of the parts shown in Fig. 5; and Fig.7, a detail showing the ball and socket connection of the rod supportingthe covering wheel.

The device comprises planting mechanisms 8, consisting of differentialdropping mechanism and shovels or furrow openers 9. The,

dropping mechanism can be of any type-of construction capable ofperforming the necessary work, and the shovel 9 can also be providedwith any form of valve mechanism suitable for the planting operation. v

The construction and arrangement of the dropping mechanism and the valvemechanism form no part of the present invention, nor are the parts of,the present invention in any way dependent upon the operation of theseparts; hence, detailed description and illustration'of these parts arenot set forth at this time. i

The shovels 9 are connected to a crossbar 10, to which are attachedlinks 11 connected to crank arms 12, which are secured to a rock shaft13, as best shown in Fig. 2. Mounted upon the ends of the rock shaft 13are segments 14, which mesh with pinions 15 on a sleeve 16, which ismounted upon a main shaft 17; and the rock shaft is rotated and held inits rotated position by lever and segment mechanism 17*. Attached to thesleeve 16, or formed integral therewith, is a lug 18 provided with asocket 18 at its outer end, adapted to receive a ball 19 upon the end ofa stem or rod 20, which rod is entered into a block 22, from whichprojects a trunnion 23 of an inner coveringwheel 24, which coveringwheel, as is shownmore clearly in Fig. 2, lies upon the inner side ofthe shovel, and one of said wheels is provided for each shovel.

Constant downward spressure is maintained upon the inner covering wheelsby means of a coil spring 25 which bears at one end against a washer 26,which is capable of being adjusted on the rod 20. Hence, by adjustingthe position of this washer, the tension of the spring can be varied andthe pressure exerted upon the covering wheels can be varied so as tocause them to enter to a greater or less extent into the ground. Thus,by means of this coil spring suflicient tension is placed on the innercovering wheels to have them perform their work in an efficient manner.

As will be seen from the drawings, the traction wheels 27 are beveledand form the outer covering wheels of the planting mechanism. Byreferring to Fig. 2, it will be seen that these outer traction wheelslie closely adjacent to the shovel of the planting mechanism, and henceare in a position to perform the functions necessary to a coveringwheel. In providing a traction wheel which serves the function of acovering wheel, sufficient weight is given to this wheel I to maintainit always in proper position to i the inner edge of the outer coveringwheel is traveling to the outer edge of the shovel, a scraper 28 isprovided for each of the traction wheels, which serves to keep the inneredge thereof free from the accumulation of dirt and While only one ofthe scrapers together with the mechanism for actuating the same is shownand described, it is understood that there is a scraper provided foreach wheel and that they are ex- In addition to being supported by therod 20, each of the inner covering wheels is supported by a rod 32,which is pivotally mounted in the block 22, as shown more clearly inFig. 4. As best shown in Fig. 2, the rod 32 extends forward to a pointadja cent to the crossbar 10 and is then bent upon itself approximatelyat an angle of forty-five degrees, whereby the bent portion will extendat approximately a parallel line -to the bar 10. And the portion of therod lying parallel to the bar has fixedly secured thereto a bracket 33which can be adjusted longitudinally of the bar 10. The bar 10 isfurther provided with a fixed bracket 34, in which the rod. 32 isslidably mounted, the fixed bracket as shown being located to the insideof the bracket 33. The rod 32 is attached to the block 22, as shown moreclearly in Fig. 4. The purpose of providing this slidable mounting forthe rod 32 is to permit adjustment of the inner covering wheel in or outfrom the center of the planter. This is necessitated because of thevariance in the width of the rows in which the corn is planted.

Taking the parts as shown in Fig. 2, in case it is desired to bring therows closer together than is shown in this position, the droppingmechanism 8 and the shovels 9 are pulled toward the center of themachine the desired distance, and the bracket 33 is loosened from theplate 10 and moved inwardly along said plate until the inner coveringwheel is in proper position with respect to the shovel. When moving thebracket 33 and the rod 32, the rod 20 will, of course, movetherewith,since both the rods 20 and 32 are connected to the block 22 as shownmore clearly in Fig. 4. But the rod 20 will swing around the pivotalcenter of the ball. 19 during such adjustment, so that it will readilyadjust itself to the proper angle given to it when the wheel is swung,without adjusting the mounting for said rod. This ball and socketconnection permits movement in any direction of the rod 20 when thewheel 24 is moved in any direction during the various adjustmentsthereof. When it is desired to raise or lower the inner covering wheels,this is done by manipulating the segment and lever connection 17*, whichwill raise or lower the lug 18. A scrap-er 34 is provided for removingthe accumulation of dirt from the edge of the inner covering wheel,which scraper is carried by the block 22.

The framework of the present invention comprises a lower frame 35 and anupper frame 36. As shown more clearly in Figs. 1, 2 and 3, these framesset one above the other. Hence, the length of the machine is materiallyforeshortened, and the weight of the body portion is centered more atone common point in the machine. By providing a short framework of thisnature, the load is brought closer to the horses, which, of course,materially lightens the draft of the machine, since the'closer theweight is placed to the neckyoke of the harness, the lighter will be thedraft. The lower framework comprises a front rail 37 which is connectedto the bar 10 by a plurality of rods 38. The main tongue 39 of themachine is secured to the bar 10 by a suitable fastening means 40, bestshown in Fig. 2, and is secured to the front rail 37 by fastening means41; and the tongue is further secured to the front rail by brace rods42. The front rail is connected, at its ends, to a bar 43, best shown inFig. 1. This bar carries and supports a pivoted plate 44, upon which aremounted the rollers 45, which engage with the knots on a check-row wire.The function and operation of these rollers are well known to anybodyfamiliar with the art and a detailed description thereof will not beentered into at the present instance.

The bar 43 is pivotally connected to a link 46 which swings about themain shaft or axle 17, as best shown in Fig. 1. As shown in Fig. 2, theupper end of this link 46 is forked at 47 and interposed in the spacebetween the forks is a collar 48, which is locked to the shaft 17. Thisconstruction prevents lateral movement of the forked end of the link 46with respect to the shaft, but permits of a swinging movement of saidlink around the shaft.

A bar 49 serves to connect the front rail 37 to the shovels. As will beseen from the foregoing description, the bar 37 swings from a pivot,which is the center of the shaft 17 since the bars 37 and 43 swing inunison. The plate 44 carrying the rollers is rigidly connected to thebar 43. There is a rigid connection between the bar 37 and the shovels,in the form of the bar 49. The shovels are rigidly connected to thecrossbar 10. The crossbar 10 is connected by links 11 to the crank arms 12.The crank arms are connected to the rock shaft 13. The rock shaft 13 isconnected to the sleeves 16, and the sleeves 16 in turn are connected tothe inner covering wheels 24. Hence, when the shovels 9 rise or fall,due to the irregularities of the 'round, they carry with them the bar 37the bar 43, the plate 44, the rollers 45, the bar 10, and the link 11,which actuates the crank arms 12, swings the rock shaft 13, whichthrough its geared connection rocks the sleeves 16 around the shaft 17,swings the lug 18, and through the medium of the rod 20 raises ordepresses the inner covering wheel. And this raising or depressing ofthe inner covering wheel is further accomplished by the swinging of therod 32, which occurs simultaneously with the movement of the crossbar10, since the rod and crossbar are rigidly connected through the bracket34. Thus, when movement is imparted to the shovel which is thefurthermost member of the planting mechanism engaging the ground,simultaneous movement is imparted to the balance of the plantingmechanism, so that they are all moving in unison and their co-relationis maintained at all times. This eliminates the objectionable feature ofhaving one portion of the mechanism rise or fall independently.

of the rest, producing a constant jarring of the parts. And, moveover,the shovel is located so closely to the center of the traction Wheels 27that when the shovels strike an uneven portion of the ground, thetraction wheels strike this portion so soon afterward that the shovelsare not thrown downward or upward when the traction wheels strike thisportion, but both of them move practically simultaneously. This preventsthe digging of the shovel too deep into the earth, or the skimming ofthe shovel over the top of the earth, both of which are undesirable inthe planting operation.

When the inner covering Wheels are raised or lowered by the actuationsof the segment and lever mechanism 17 the crank arms 12 are moved,moving the links 11 and the bar 10, which raises the runners 9 and frontrail 37, which in turn raises the bar 43 and plate 44. Thus the entireplanting mechanism is raised or lowered simultaneously.

'The upper frame comprises a front rail 50 and side rails 51, shown moreclearly in Fig. 2. As shown in this figure, these rails are all formedfrom the same piece of metal; but, of course, this construction may bechanged and they may be formed of separate pieces if desired; The upperframe is secured to collars 52, best shown in Fig. 3, which are looselymounted upon the rock shaft 13. The side rails 51 of this upper frameextend beyond the collars 52, as best shown in Fig. 2, and have theirends connected to a seat 53. Sidewise movement of the upper frame withrespect to the lower is prevented by arms 55 joined to the side rails ofthe frame. These arms 55 rest against the sides of the links 11, as bestshown in Fig. 3.

Attached to arms 56, loosely mounted on the rock shaft 13, are the endsof bars 57, constituting a stub tongue 57 the other ends of these barsbeing connected to a clip 58, best shown in Fig. 1. The bars 57 of thestub tongue, as more clearly shown in Fig. 2, overlie the rails of theupper frame and are secured to the front rails 50 by a suitable clip 59.The point of juncture between this stub tongue and the main tongue isapproximately midway the length of the main tongue, bringing it close tothe center of movement of the entire planter, which is, of course, thepoint of juncture between the main tongue and the neckyoke of theharness. By this construction the upper frame is supported by the stubtongue, which is supported by the main tongue, and the upper frame inturn supports the rock shaft 13.

When the wheels, shovels, and planter mechanism are lifted from theground a certain distance, but a very slight portion of this movementwill be communicated to the upper frame. This is because of the factthat the movement at the point of juncture of the stub and main tongueswill be-slight, since this point is close to the center of movement ofthe entire device. Hence the movement communicated to the upper framewill be slight; and since this is the movement which directly affectsthe operator, the seat being carried by this upper frame, to allpractical purposes, jolting of the operator will be eliminated. This isconsidered to be an important point in the present invention, since inall prior constructions, so far as I am aware, the connection betweenthe frame carrying the seat and the frame carrying the plantingmechanism has been far removed from the center of movement of the entirevehicle. Hence, the same degree of movement was imparted to the seat aswas imparted to the traction wheels when the latter passed over anuneven portion of the ground.

By referring more particularly to Fig. 2, it will be seen that thecenter of the weight of the planting mechanism is the center of theshaft 17. This is because the bar 43 is connected to this shaft 17. Thefront rail 37 is connected to the bar 43; the shovels 9 are connected tothe rail 37; the rail lO is connected to the shovels 9; and the innercovering wheels are connected to the rails 10 through the medium of thelink, crank arm, and gear connection heretofore described. Thus, theentire planting mechanism is carried by the front rail 37, which isconnected to the bar 43 hung fro-m the shaft 17 and the weight of theplanting mechanism is centered at a point forward of the shaft 17although it is bearing upon the shaft 17. The weight of this mechanismtends to draw the main tongue 39 downward, this tongue being connectedto the front rail 37 and the crossbar 10. The center of the weight ofthe operator, when he is in pro-per position upon the seat, is the pointof juncture between the main tongue 39 and stub tongue 57 The weight ofthe operator will tend to raise the front rail 50 of the upper frame 36,said weight being placed to the rear of the rock shaft 13, about whichthe upper frame swings. This in turn will raise the stub tongue 57*,since these two members are connected by the clip 59. The weight of theoperator will tend to raise the forward end of the stub tongue, and thismovement will tend to raise the main tongue 39. Thus the weight of theplanting mechanism tending to lower the main tongue will becounterbalanced by the weight of the operator, which will tend to raisethe main tongue, and the weight of the body of the machine upon theneckyoke of the horses will be but slight.

A support is provided for the ends of a rock shaft 60, which operatesthe clutch mechanism 61 of the differential dropper. The rock shaft 60,as shown more clearly in Fig. 2, telescopes within a tube 60*. This isto allow of an adjusting movement of the seed boxes. There is a featherkey or other suitable connection between these parts so as to insuretheir unitary rotation. This clutch mechanism and dropper and thefunctions of the rock shaft do not enter into the present invention, anda detailed description thereof is not given at the present time. Therock shaft is provided, on its end, with a crank arm 62, which operatesthe valve in the shovel. This valve mechanism and its principle ofoperation is not a part of the present invention and is not described orillustrated in detail.

As best shown in Fig. 5, the crank arm 62 is provided with a lug 63,which is engaged by a pin 64 extending through the rock be movedsimultaneously with the rock shaft when said shaft is oscillated in onedirection, but permits of a non-action of the arm 62 when the shaft ismoved in the opposite direction. A support for this shaft is formed bythe bar 43, although the shaft is not actually mounted within said bar.The connection between the bar and the shaft is as follows: A casting 65is provided, which consists of a body portion 66 having an opening 67through which the shaft passes. The body portion has two of its facesfinished to receive the ends of the angle iron constituting the frontrail 37, and said rail is bolted or otherwise secured to these faces.Upon the sleeve 68 is mounted an upwardly extending lug or finger 69, towhich is attached the bar 43.

It is understood that the shaft 20 is not keyed or secured in any way tothe casting 65 or its component parts, and in order to prevent sidewisemovement of the lug 69 upon the sleeve 68, a projection 70 is formed onthe sleeve 68, which rests against the side of the lug and preventsmovement in one direction, movement in the other being prevented by theengagement of the lug with the body portion of the casting, as bestshown in Fig. 5.

In order to position the lug upon the sleeve a hole 71 is provided inthe lug of a size to fit over the projection 70, and after it has beenslipped over, the lug is given a quarter turn so as to bring the partsinto the relative positions shown in Figs. 5 and 6. This arrangementpermits rotation of the shaft 60, which rotation does not afiect any ofthe supporting parts of the planting mechanism, and the mot-ion of thesupporting parts does notaffect the rotation of the shaft 60.

As shown in Fig. 2, a cable 72 operates the catch to release the plate4.4 and allow the rollers 45. to separate and release the check wirerollers. This cable, as shown, passes through a guide 73 secured to therail 37 and passes along the frame in front of the hoppers containingthe grain.

A plurality of holes 58 are provided, as shown in Fig. 1, which permitof the adjustment of the bracket member 58, thus placing the point ofjuncture of the main and stub tongues nearer or farther from the forwardend of the main tongue, in order to regulate the distance of the furrowopeners from the point of ground contact of the traction wheels. Wherethe term. runners is used in the claims, I intend to include furrowopeners generally, unless otherwise indicated.
